When using external voltage sense, sense wires must be connected between the rear panel
External voltage sense terminal and the load. These wires do not carry any load current so
can be sized accordingly.
Note: If the external sense connections are not used, the power source will use the local
(internal) sense points at the output terminals instead to sense the output voltage.
This means the sensed voltage may be higher than the voltage at the load as load
wire voltage drops is not compensated when using internal sense.
Note: For AFXT Models, the sense connector is normally connected to the Transformer
Option chassis. In this case, the external sense connection is made rear panel of the
Transformer option chassis. If the Transformer chassis is not present, the External
Voltage sense inputs on the rear panel of the AFXT power source MUST be
connected to either the output terminal or the load at all times or an open sense
fault will occur.
Note: AFX-2L and AFX-4L Model Units (L version) are shipped with the mating External
Voltage Sense connector installed and screwed in place to act as a safety cover.
When the external voltage sense connection is not used, this connector should be
left in place.
AFX(T)-2A and AFX(T)-4A Model units (A version) use a Push-in spring connection
type external voltage sense terminal that requires no mating connector. Use a small
screwdriver

to push in the locking mechanism, push in the stripped sense were
ends and pull out the screwdriver to lock the wire in place. See for reference.

For three-phase sense connection wiring, refer to Figure 5-7 for 3 phase WYE load
connections and Figure 5-9 for three phase DELTA load connections.
